San Kan Oh Functional Water units clean electronic components

Do you need to clean electronic components quickly and efficiently?

We have recently received orders for another 6 model H-300 San Kan Oh units from a long-term client.

What are San Kan Oh units?

Basically, San Kan Oh is a range of products that deliver different types and flows of so-called “Functional Water”.

Functional Water does just what the name suggests; it performs a cleaning function, ensuring that every component is clean and free-from impurities.

San Kan Oh units deliver different types of Functional Water that are specifically used to clean electronic components.

Electronic components need to be cleaned to virtually unbelievable quality standards if they are to perform their intended function and also have long-life.

Traditionally, for many years component cleaning has been done using a range of strong chemicals, depending on what the component is and what impurities need to be removed.

The cleaning process involves:

  • Purchasing Strong chemicals (including acids, alkalis etc)
  • At the end of the cleaning cycle, rinsing those chemicals from the components. This involves the use of large quantities of Ultrapure Water, which is expensive to produce.
  • Purchasing chemicals to neutralise those strong chemicals that are discharged in the rinse water.
  • Paying for the removal of the solids produced on neutralisation.

All of this is expensive!

What is Functional Water?

Functional Water is Ultrapure Water (UPW) to which a small concentration of a pure gas has been added (in this case hydrogen). This makes the now – “Functional” Water able to clean electronic components very efficiently without the need to use strong chemicals.

This means that you lower your operating costs very significantly! But ALSO, Functional Water does the job very quickly. So, there is also the possibility of increasing output!

New Order for Ammonia Functional Water Units

We have recently received a new order from an existing client for 3 San Kan Oh production units, each producing up to 2,400l/h of Ammonia Functional Water.

These units use Ultrapure Water and add a small concentration of a chosen gas (in this case Ammonia) to it. This  highly active media cleans  electronic components very efficiently.

Advantages of San Kan Oh units

Using Functional Water to clean electronic components has a number of very significant advantages:

  1. You virtually eliminate consumption of traditionally-used strong chemicals used to remove contaminants.
  2. Consequently, the consumption of chemicals to later treat / neutralise those cleaning chemicals is virtually eliminated.
  3. Consumption of Ultrapure Water to rinse the components clean reduces significantly. This is simply because you do not have to remove large quantities of strong chemicals from the components.
  4. Reduces product rejects.
  5. Cleaning time reduces.
  6. Sludge production reduces dramatically.
  7. Operating costs reduce significantly.

Clearly, these advantages can have a significant effect on overall production efficiency.

We supply a number of different types and sizes of Functional Water units within the San Kan Oh range. The other most commonly used one adds hydrogen gas to the Ultrapure Water.

Another new SecureChem™ system is commissioned and operating


Chemical Dosing from IBCs

Chemical dosing from IBCs can result in a lot of expensive chemical being wasted. An increasing number of clients find this frustrating, and expensive. The wastage is simply because they have to change the duty IBC to a new one while an operator is available. This is often a problem when an IBC becomes empty overnight. If that happens, then the risk to continuing production is very real! The only way to avoid this would be to have an operator standing by and waiting for the IBC to become completely empty and then changing it instantly! – and even then there will be a short period when the chemical is then not available.

H+E’s addressed this issue by developing the SecureChem™ system. It also minimises the hazards to operators when dealing with dangerous chemicals.

Automatic Switchover

For this customer, the system handles two different chemicals. It connects two IBCs of each chemical in duty / standby mode. The system automatically switches supply to the standby IBC once the duty IBC is completely empty. When switchover happens the system also generates an alarm to advise that replacement of the empty IBC is necessary. Since each IBC holds 1,000 litres of chemical, it takes some days to consume the chemical. Therefore changing the now-empty IBC is not urgent.

Outside Installation

In this case, the SecureChem™ system is installed outside. Therefore the enclosure around the unit (that includes a heater) protects against frost, and an alarm advises of any future leakage. Dual-containment pipework provides additional safety when pumping the chemicals through the factory to the point of use.


SecureChem™ systems are supplied in a range of materials. This depends on the chemicals used and perhaps on your own in-house requirements. Typically, pipework would be PVC or ABS. However, other materials such as PP, Pe, PVDF and stainless steel are also available.

Supply and Installation of Lamella Tube Modules

We have recently delivered and completed the installation of replacement Tube Modules for a Lamella Clarifier originally built in 1991. The clarifier handles wastewater produced by a Combined Heat & Power plant. On the agreed date we delivered the Tube Modules. We installed them a day earlier than planned. Consequently we put the clarifier back into service a little earlier than anticipated.

Advantages of Tube Modules

You really can improve the efficiency of solids settlement in a Lamella Clarifier by using our Tube modules. They:

  • Ensure laminar flow across the whole surface area of the tank, therefore avoiding local areas of high upward velocity which would prevent efficient settlement.
  • Increase the effective area for solids settlement, typically by 8:1, consequently improving settlement efficiency.
  • Allow small solids that do not settle easily to flocculate with each other, after which they then settle.
  • Therefore minimise the floor area that you need to allocate for settlement

Over 40 years of use has proven the efficiency of H+E’s Tube Modules. Many hundreds of plants across Europe use them.

Strong and Long-lasting

Within the modular pack, each tube is inclined at 60°. Each row of tubes is inclined in the opposite direction to its neighbour rows. Consequently, flow distribution across the tank is good and also makes the Tube Modules strong.

Fabrication in ABS ensures they are light, hence easily lifted by two people, and have a long service life.

The tubes themselves have a square cross-section. Therefore there are no “tight” angles to easily trap solids. This maintains their operating efficiency for the long-term.

You can increase operational efficiency by retro-fitting Tube modules into existing clarifiers.


When you need high efficiency settlement of solids, Tube Modules are an appropriate solution in more or less every case.
